check_disk doesn't connect to remote machines or understand a -H
parameter.

127 means the plugin isn't in the location Nagios is told it lives in.
Is the value of $USER1$ set to /usr/local/nagios/libexec in
resource.cfg? Is resource.cfg included as a resource_file in nagios.cfg?

I suspect you corrected the above $USER1$ error but now you're seeing
the effects of using '-H $HOSTADDRESS$'. When run from the command line
--

$ ./check_disk -H 99.99.99.99 -w 10% -c 5% -p *
./check_disk: invalid option -- H
Unknown argument
Usage: check_disk -w limit -c limit [-p path | -x device] [-t
timeout][-m] [-e] [-W limit] [-K limit] [-v] [-q]

You can always find the parameters a standard plugin understands by
running the plugin with '--help'. You should continue to test from the
command line until you get the parameters right (hint: -p * isn't going
to work as you think it is; you might not even need it).

Nagios does not verify that the plugins you specify actually exist. If
they do not, you see the 127 return code as above when it tries to use
it.
